Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic valve sealing, and specifically relates to an electromagnetic valve sealing structure. BACKGROUND

[0002] An electromagnetic valve is an automatic control device that uses electromagnetic control to realize the switching or regulating function of fluid (such as gas or liquid). It drives the internal mechanical components (such as a valve core) to act by the magnetic force generated by the electromagnetic coil, thereby realizing the on-off or flow regulation of the medium in the pipeline. The sealing structure of the electromagnetic valve is a key part inside the electromagnetic valve for preventing fluid (liquid, gas or steam) leakage, ensuring reliable sealing of the fluid when the electromagnetic valve is opened and closed.

[0003] The sealing structure of the electromagnetic valve disclosed in the patent document with the publication number CN219198261U replaces the traditional bolt connector with a U-shaped connector. During installation, only one connecting bolt needs to be turned to complete the connection or disassembly of multiple connection hole positions, improving efficiency during installation or disassembly of the electromagnetic valve. The connecting bolt for connecting the connecting plate is located outside the valve body flange, avoiding internal thread slipping of the connector. When disassembly is not possible, the connecting bolt or connecting plate can be directly cut off without damaging the electromagnetic valve, avoiding a decrease in the sealing effect of the electromagnetic valve.

[0004] The above technology has the problem of easy loosening. Although the above technology replaces the traditional bolt connector with a U-shaped connector, the connection is still achieved through a bolt. The bolt may loosen over time due to environmental changes during use, resulting in a decrease in the pre-tightening force between the connected components, which can damage the sealing effect and cause fluid leakage.
